Fig. 4: COMSOL simulation of adsorption processes in different adsorbents.

a Cloud maps of the flow velocity field of IM-PAO, LP-PAO, and HTC-PAO. b Comparison of adsorption concentration cloud maps of IM-PAO, LP-PAO, and HTC-PAO. c Comparison chart of simulation results and experimental data. d–f Mass transfer resistance analysis of uranyl ions during the adsorption of IM-PAO, LP-PAO, and HTC-PAO. The total transfer resistance consists of three parts: the convection transfer resistance at the external surface (\({R}_{{\rm{surf}}}\)), the diffusion transfer resistance within the porous adsorbents (\({R}_{{\rm{diff}}}\)), and the apparent reaction resistance at the sorption interface (\({R}_{{\rm{react}}}\)).
